BARREL SEAL.

Application, filed August 26, 1921. Serial No. 495,464.. i

of heavy compounds such as road oils or the like.

Hitherto in transporting such materials in barrels and casks it has been the practice to knock off the barrel heads in order to i remove the contents quickly. Thus the barrels have thereby been damaged to an extent that they could not be used again and the consumer has been deprived of rebates on barrels which it is the custom to allow for the return of barrels in good order. This has resulted in considerable loss to the consumers and-in the destruction of large quantities of barrels.

Broadly stated it is the object of the present invention to provide means for sealing barrels containing such materials so as to permit the contents 'to be discharged quickly and efiiciently without impairment of the barrel, and so as to permit the barrel to be used for subsequentshipments.

One of the features of the invention comprises a. frame secured to the barrel head and a closure for the barrel opening therein slidable in the frame. 1

Another feature relates to fastening means for securing thelseal tightly in po'-- of adjustable means for the closure device,

so that a tight seal may be effected inclependent of variations or tolerances of construction.

Other objects will appear as the description of the invention progresses.

Referring to the drawings:

Fig. 1 shows a plan view of a portion of the top of a barrel or place. 1

. Fig. 2 is a section taken on the line 2 2 'ofFig. 1. p 1 y Fig. 3 is a section taken on the line of Fig. 1.

Like reference characters denote likeparts "w;

in the several figures of the drawingx cask" with a seal in Referring to the drawing, a preferred embodiment of my invention comprises a frame 10 secured to the barrel head in any suitable manner as, forlexamplaby wood screws. Attached to the frame 10 as shown in Fig. 1 is'a' pair of elongated flanges-or guideways 11, 12, which extend parallel to one another in spaced relation to maintain a slide 13 in position. between them.

The slide is provided with an over-hung end portion 14 which is bent around into a plane parallel with and spaced from the main portion in order to form a seat against slide. The other end of thebar 15 is provided with a notch and may thereby be secured by a bolt or lagscrew 16, extendingthrough-the oppositely positioned flange which force may be applied to move the 12. In an intermediate position of the portion of the bar 15 is a set screw 17 arranged to press the slide the barrel head.

The barrel is provided with an opening 20 sufliciently large to permit the escape of heavy compounds such as road oil or the like. It will be seen that-the slideplate 13 is arrangedto slide over the opening 20,

plate 13 securely against as shown by the full lines 'ofFig. 1, and y when in suchposition maybe tightly secured against the opening by screwing down the said screw 17 The strain is carried by the bar 15 and the bolts at the points 14 and 16 and a very tight closure can be effected. 1 I

In order to open the barrel, the set screw 17 and the bolt head 16 are turned back and the bar 15 is rotatedinto the position shown by'the dotted lines of Fig. 1., The

slide plate 13 is'now' shifted to the positorelease the slide plate from the compound and this can readily be done by the use of tion l t, or by inserting a bar or lever in the hook form by the portion 14 and prying it loose. The open position of the slide plate 13 is shown by the dotted lines of Fig. 1. The contents of the barrel may be discharged through the large opening 20 and the barrel returned for subsequent use.

It will be seen that an extremely tight closure may thus be provided by means of a relatively inexpensive and simple structure. The entry of dust and dirt into the barrel content during shipment is eifeetually prevented and the labor of opening the barrel and discharging the contents thereof is materially reduced.

Apparatus of preferred. form and construction has been illustrated and described for the purpose of showing away in which this invention may be practiced; but the inventive thought upon which this invention is based is broader than this illustrative embodiment. For example, the device may be used with barrels made of metal by extending the frame 10 to the edges of the barrel head and providing flanges to engage the usual flanges on'the barrel, and other modifications may be made without departing from the spirit of the invention. It is, therefore, understood that the scope of this invention is not limited by the present disclosure, referenc being had to the appended claims for that purpose.

lVhat is claimed is:

1. In a seal for a barrel, a frame secured. at one end of the barrel, a pair of parallel spaced guideways secured to the frame, a

slide supported. within said guideways adjacent said frame and adapted to slide into and out of an engagement with the barrel opening. abarpivoted to one guideway and adapted to be'secured to the other guideway, and means engaging said bar and slide to secure the slide in tight position against the opening.

. 2. In a seal for a barrel, a pair of parallel spaced guideways, a member slidable be tween said guideways and arrangedto be positioned over the barrel opening, a bar pivotally mounted on one side of the opening. means for securing'a' portion of the bar on the other side of the opening and means cooperating with an intermediate portion of the bar for securing the slidable member in tight position overthe opening.

3. In a seal for a barrel, a pair of spaced parallel guideways, a 'slidepositioned between said guideways and arranged to cover the opening. of the barrel, a bar mounted on one side of t'hej opening, means for securing the ends of the bar at points; opposite the opening, and means cooperating with an intermediate portion of the bar for securing the slide in tight position over the opening.

4. In a seal for a barrel, a frame secured to the barrel at one end thereof, comprising a pair of parallel spaced guideways, a member slidably supported between said guide- Ways adapted to slide into and out of engagement with the barrel'opening, and a bar removably secured to said guideways and adapted to maintain said member in tight position against the opening.

5. A. seal for a barrel, comprising a slidable member arranged to be positioned over the barrel opening, guide; members for the slidable member and means for securing said member in place, said member having an over-hung portion whereby force may be applied to displace the slide.

6. A sea]. for a barrel, comprising a subs'tanti ally fiat slidable member arranged to be positioned. over the barrel opening, guide members therefor, and means for securing said member in tight position over the opening, said member having an end portion bent through an are into a plane substantially parallel with and spaced from the remaining portion of said member.

7. In a seal for a barrel, a frame secured to the barrel at one end thereof, a pair of parallel spaced guideways, a member having substantially flat portion slidably supported between said guideways adjacentsaid fraine'and adapted to slide into and out of engagement with the barrel opening, a bar pivoted to one guideway and adapted to be secured to the other guideway, and means engaging said bar and slidable member to secure'the slidable member in tight position against the opening, said slide having an end portion bent through an are into a plane substantially parallel with and spaced from the remaining portion of said slide.

8. In a seal for a barrel, a pair of parallel spaced guideways, a member having a substantially fiat portion slid-able between said guideways and arranged to be positionedv over the barrel opening, a bar pivotally mounted on one side of the opening, means for securing a portion of the bar on the other side of the opening, and means cooperating with an intermediate portion of the bar for securing the slide in tight position over the opening, said. slidable member having an end. portion bent through an arc intoa plane substantially parallel with and spaced from. the remaining portion of said member.

In Witness whereof I have hereunto set my hand and seal th'is QZnd day of August 1921.
